Anti-friction alloy



UNITED STATES PATENT OFFICE.

SAMUEL SI NQLEY, OF NEW YORK, N. Y., ASSIGNOR TO THE MAGNOLIA ANTI-FRICTION METAL COMPANY, OF NEW YORK.

ANTI-FRICTION ALLOY.

SPECIFICATION forming part of Letters Patent No. 429,158, dated June 3, 1890. Application filed June 22, 1889- Serial No. 815,249. ($pecimens.)

To all whom it may concern.-

Be it known that I, SAMUEL SINGLEY, of the city, county, and State of New York, have invented a new and Improved Anti-Friction Alloy, of which the following is a specification.

My composition consists of the following metals, in the proportions substantially as stated:

Lead 80 pounds.

Antimony 15 Tin 5 Bismuth i Aluminium. i

100{-say 100 pounds.

The lead, when molten, I prefer to cleanse by the application of sufficient sal-ammoniac. This I do by adding gradually four to eight ounces of sal-ammoniac, mixing thoroughly, and keeping the molten mass stirred, and removing the scum and dross as it rises; and I also prefer to treat the lead and antimony with sufficient powdered graphite to cover the molten mass, stirring repeatedly, as I have found such treatment to produce better results. If the lead is pure, or has been previously cleansed, the sal-ammoniac may be omitted.

What I claim, and wish to secure by Letters of the United States, is

The composition of matter to be used for anti-friction purposes, consisting of lead, antimony, tin, bismuth, and aluminium, substantiall y as described.

SAMUEL SINGLEY.
